This study explored the capability of treating real dairy wastewater using the microbial electrochemical system by using Lactobacillus plantarum   species as a microorganism. The samples were collected from a local factory for dairy products in Baghdad. Three main parameters were investigated with different levels, for estimating chemical oxygen demand (COD), phosphate (P) and nitrogen (N) removal efficiency. The studied parameters were detention time, the potential difference between electrodes and initial concentration of COD. The respective optimum values for these parameters were 17 days, 400 mV and 17000 mg COD/L respectively. At the optimum values, the optimum COD removal efficiency was 99.4%. Meanwhile,

This study aims to obtain information on the reproductive biology of these species, especially on sex ratio, fecundity, ovarian development, and breeding season. The study was conducted from August 2022 to July 2023 on every full moon with the highest tide in the estuary of Bengawan Solo River, East Java, Indonesia. The obtained samples were placed in the freezer and identified, and a dissection was performed to observe the gonads. There were 617 crabs with an average sex ratio of 1 male to 1.9 females. Mean fecundity of V. litterata was 45350±3182 egg/individual. In each sampling period, there were always females that were maturing gonads. The ovaries of females during the study were the early developed (stage III), la

By utilizing Ni-NTA affinity chromatography, the expressed recombinant HSP70 protein was purified, and the SDS-PAGE analysis was used to assess its purity. Purified recombinant HSP70 was used to immunize BALB/c mice, and this had a considerable impact on the anti-HSP70 antibody titers. The results of this study show that the adjuvanted hsp70 injected into the mice had a good immunogenic property. In this study, we measured the effects of HSP70 on catalase stability after exposure it to different range of temperature (40, 45, 50, 55, 60) ˚C, and found that the catalase kept its remaining activity% (99% and 17%) when incubating it in 40 and 60ºC respectively in the present of HSP70, compared to its remaining activity % without HS

The mean infection percentage of this group ranged from 0.28-3.98% and significantly was higher than

Vegetation diversity patterns are necessary to identify species of plants in the Zawita mountains area, Duhok Governorate, Iraq, to investigate the influence of topographical elements (aspects - north and south, elevations and slope gradients) on diagnosis, density, frequency, and species richness and diversity of species in the Zawita forest understory vegetation. Sampling vegetation was surveyed at (1 * 1 m^-2), for 8 quadrats per each zigzag transect. The data were designed with a strip-strip block design, with four replicates for each transect. The results revealed significant differences in frequency, density, and Shannon index due to aspects, elevations, and slope gradient. While other measured traits, species ric

This study was aimed to investigat integrated system for in vitro growth of paulownia plants by assessing the efficacy of chlorine dioxide (ClO₂) as an alternative to autoclave in sterilizing culture medium. Therefore, this study was devised to compare autoclave sterilization at three different times (5, 10, and 15) minutes and three different concentrations of ClO₂ (0, 0.4, 0,8, 1) mg/L. The results showed that, compared with (0.4) mg/L concentration,  concentrations of (0.8 and 1) mg/L are more effective at sterilizing the culture medium. ClO₂ sterilization improved individual single node growth more than autoclave sterilization. Since ClO₂

This study was aimed to test four types of different plants for the purpose of selecting the optimal plant as a source of the amylase enzyme, including wheat, barley, rice, and potatoes. Among these plants, wheat was selected as the best plant source for enzyme extraction because it possessed the highest effectiveness of the enzyme specific activity (3.0 U/mg protein). Furthermore, sodium acetate buffer (0.2 M, pH 6.0) was determined to be the optimal extraction buffer with a 1:5 (w:v) ratio after 75 min, and it provided 68 U/mg protein. The enzyme was concentrated with sucrose before being purified by gel filtration chromatography using Sephadex G-150. The results demonstrated a 1.8-fold increases in final purification folds wit
